I bought a used TRX that didnt have the battery and the wiring in box is a mess. I was wondering when attatching new terminal posts which side is positive and which is negastive.
Also there is one unconnected white connected at the bottom I was wondering if that was used for something necessary?
Pos post is connected to the solenoid. Negative should go to earth. Not sure what a spare white would be for, if I can remember, I will check the wiring diagram at work.
